What is the built-in measuring instrument ranges in?
I did not find this information in the description or in the schematic.

The schematic shows a meter marked ± 50. I believe this means it is a meter in which the needle is normally centered in the middle of the meter when there is no signal. But When there is a positive 50 milliamps current, the needle will move fully to the right side, and when there is a negative 50 milliamps current, the needle will move fully to the left side.
